Along with this recipe Kendor has quite a few more, some that you'd usually get from quests , so if you don't feel like doing the quests for them this is an easy way to get a new recipe. :)

Post-shattering report: Heldan Galesong does NOT sell this recipe anymore. He's kind of dead/missing now. Good news though, you can still get this recipe from Kriggon Talsone in far SW Westfall at a place called Westfall Lighthouse. And yes, it is still Alliance-only. And no, Nessa Shadowsong does not appear to sell this post-Cata either.

*Updated as of 4.2.2 and just pre-4.3.

For Hordies, here's one way you can get the recipe from the vendor for yourself or to sell to other Hordies:

1. Make an alliance rogue. I chose Human because Stormwind is closer to Westfall and the vendor than your other options, but not that big of a deal.

2. Get 11 silver for each recipe you want to buy (8 for the recipe itself, 3 to list it on neutral AH). If you do quests to get the money, you'll get to level 6 or 7 before you get 11 silver.

3. Learn Stealth at level 5.

4. Stealth your way through Westfall through roads and/or along the coast. If you stay on top of the ridge/hills next to the coast, stealthed, you will easily weave your way through everything that might otherwise attack you.

5. Buy the recipe from Kriggon Talsone, who is sitting on a dock on the south end of the shore.

6. Swim south to Booty Bay. Try to stay as far away from the coast as you can. Doing this, I was only attacked once by some underwater murloc-types, but I rezzed far enough away from my death spot to avoid them after.

7. List your recipe on neutral AH, and have a guildie or friend ready to buy it instantly to trade to your Hordie.

Of course, if you already have an alliance character (that flies?) this will be much, much easier. If you don't, you can do this.
